I drove 1300 round trip miles to purchase an early 1970 engine with no center front head bolt. It's a replacement diecast case, it has the recall punches but no serial numbers. The rockers have the early single notch on the rocker shafts rather than the wasp waisted notch seen later. The oil jets don't remove and the vertical pins in the fins protrude through the bottom fin like a later K0 or K1 motor. The head's cooling fins fins are brittle not bendable like a sandcast head. there is one broken. It has the heavy flywheel too.
This gives me enough parts to rebuild a correct K0 motor for my 14,100 frame. It has a fairly hot, ported and cammed K4 836 in it now, I'm conflicted about taking it out. lol.
The original tank, repop sidecovers and related trim are ready for paint, now I need to sell something to pay for it.
I also picked up a rough but repairable single cut fender and a set of K1 gauges, they had chrome covers, I was hoping to find K0 gauges in there. Fooey.
